SUBROUTINE BLANKT(nframe)INTEGER*4nframe

Description

The blanktime subroutine changes the amount of time the system waits before it blanks the screen to protect the color display. The default delay before the screen turns black is 15 minutes after the last input. This subroutine can also disable the screen-blanking feature.

To calculate the value of the nframe parameter, multiply the desired blanking delay period (in seconds) by 60. For example, when nframe is 18000, the blanking delay period is 5 minutes. If there are 60 frames per second, nframe is 60 times the number of seconds that the system waits before blanking the screen. To disable screen blanking, use 0 (zero) as the value for nframe.
